If we had to pick who would win in a fight — rock star Shirley Manson or pop diva Jennifer Lopez — we might have gone with the angst-filled red head.

However, never underestimate what a Bronx upbringing and a $150 million net worth will do to a girl because the Garbage singer admitted she is no match for "alpha dog" J. Lo!

While chit-chatting with Aisha Tyler on her podcast, Manson recalled a super awkward moment with Lopez at a Vanity Fair photoshoot.

The Only Happy When It Rains singer had been "very rude about her in the press" and even mentioned that she wanted "to punch her in the face," but when the opportunity came to take a swing…

Well, we'll just let Shirley do the talking. Here's the story in her own words:

"I was standing with my back to the main set, and she hadn't arrived on set yet. And then all of a sudden I felt this kind of… all I can say is that the energy changed and I turned around here was J.lo strutting towards me in all her glory and I was thinking 'Oh f*ck, here we go. The fly girl is literally going to fight me.' That's what she looked like… like she was going to take me down. And she just thrust out her hand and said 'Shirley' and I said 'Yep' and she went, 'Jennifer.' And I said 'Hi, Jennifer' and I shook her hand and then, I kid you not, she walked backwards and kept eye contact until I dropped my eyes and looked away. It was so alpha dog and I had to play submissive dog. And I had so much respect for her after that. I was like, 'Okay. You took me down. I gotta give it to you.'"

Exactly! Bow down bitches to our Queen! I'm happy Jen left AI this year! She was so classy, sweet and beautiful, i wouldn't like seeing her with these trashy cows! But make no mistake! Mess with her and she'll go all Bronx on your ass bitch!

Lol, I remember reading the interview where Shirley had said she wanted to punch JLo in the face. I can't remember exactly what she said but it was backstage at some award show and Jennifer had a diva moment. She also said Lopez wouldn't need to spend so many hours in the gym if she could write songs like Fiona Apple. I'd still choose Shirley.
